Effects of microbial loading and sporulation temperature on atmospheric plasma inactivation of Bacillus subtilis spores

Current inactivation studies of Bacillus subtilis spores using atmospheric-pressure glow discharges APGD do not consider two important factors, namely microbial loading at the surface of a substrate and sporulation temperature. Yet these are known to affect significantly microbial resistance to heat...
